IMPRovEMENT IN coNDUCv'roRs PUNcI-IES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all lwhom it may concern:

Be it known that we, J 01m FRLesE and GEORG DANIEL FnrEsE, of the cityand county of Baltimore, and State of Maryland, have invented a new andimproved Conductors7 Punch; and we do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the accompanying drawings,making a partof this specification, in which-A Figure 1 is a side view,a portion of one of the jaws having been broken away Figure 2 is anedge4 view.

The obj ect of this invention is to so improve 4the common instrumentfor cutting eyelets in paper, leather, cloth, 85o., that the spring thatforces the jaws apart will not wear out, or get out of order sol soon,while the piece punched out of the paper, leather, 86e., will be ,morecertainly and eectually removed from the tooth or cutter.

In the drawings-'- p A represents the jaw which supports the tooth orcutter a., and I 'B, the opposite jaw, having an opening, e,corresponding in shape to the cutting-end of the tooth a, the two jawsbeing crossed and pivoted together at b, and their ends, opposite to thetooth and eye, being fitted to be grasped and held easily in the hand.

To the jaw A, at c, is attached a bent spring, O, which presses againstthe opposite jaw, and serves to open them. f

To the jaw B, at n, is attached a steel plate, M, eX tending out beyondthe tooth a, then bending round over the extremity' of jaw A, in theshape of a hook, as seen at m m 'm2, and, by thus extending over .theend o jaw A, preventing the two jaws from being opened so far as, inshutting again, to damage spring G, or wear it out too fast. v

The plate M is provided with an opening, through .which the tooth apasses when the instrument is used,

and as the jaws open, after cutting the eyelet, the tooth draws backthrough said opening, and causes the plate to scrape from it the pieceof paper or other material punched out, and thus to clean tne'tooth andprepare it for another operation.-

The plate M is fastened to jaw B by means of a screw-rivet, a', andcantreadily be removed. It rests upon a slightly-raised bed, s, so thata snicient space shall be left between the body of it and the jaw B, toadmit between them the leather, cloth, or other material to beoperatedupon.

The bent end, m m, servesnot only as a part ofthe hook that extends overthe end of the opposite jaw, but also as a guide .to facilitate theinsertion of the material to be punched.

The ,hook fm?, when the jaws are opened, comes in contact with the jawA, between two slight projections or lugs, i i, at its extremity, whichprevent the springing or twisting of the parts, and keep the instrumentfrom getting out of order. l

The tooth a may be made detachable, and removable, if preferred, so thatif it should get out of order, from any canse, it may be removed, andanother inserted. To this end, it might be screwed into .thel jaw, orany other construction might be adopted which would answer the purposeas well.

Having thus described our invention, i

What we claim as new, and desire to secure by Letters Patent, isv Inconnection with the eyelet-cutting instrument, having the two jaws A andB, the tooth a, the opening e, and the spring C, the rigid plate M, whenattached to the jaw B, upon a raised bed, s, and provided with theopening to receive the tooth and bent s o as toV hook over the end ofjaw A, the several parts being constructed to operate together, in themanner and for the purposes herein set forth.
